Letters Tateni. 

is SOON as an inventor 
has perfected his device 
he naturally seeks pro- 
tection which will se- 
cure to him the profits 
of his invention and 
•give a just reward for 
his industry, skill and genius. 

Such protection is afforded by Letters 
Patent. 

They give the inventor the exclusive right 
for the period of the patent to make, use and 
sell his invention. 

United States patents bear date of the 
day they are issued, and, except in the 
case of designs, are granted for the term of 
seventeen years from that date. They afford 
protection for the invention for which they 
are granted from the date of issue. 

Patents cannot be extended except by act 
of Congress. 

What May Be Tafented. 

A patent may be obtained by any person 
who has invented or discovered any new and 
useful art, machine, manufacture, or compo- 
sition of matter, or any new and useful im- 
provement in them, not known or used by 



others before his invention or discovery, and 
not patented or described in any printed 
publication before such invention or discov- 
ery, or more than two years prior to his ap- 
plication, and not in public use or on sale in 
the United States for more than two years 
prior to his application, unless the same is 
proved to have been abandoned. 

T^relitninary E^jcaminaiion. 

Before going to the expense of filing appli- 
cation for Letters Patent, it is usually advis- 
able to have a preliminary examination made 
in the Patent Office of the patents in the 
classes to which the invention pertains, to 
ascertain if there are any which will prevent 
the grant of a patent on the invention in 
question. 

To enable me to make such an examina- 
tion, the inventor should send a plain sketch 
or drawing, or a model, and a clear descrip- 
tion of the invention and its operation. 

The drawings need not be precise or artis- 
tic, but should clearly show the details of the 
device, and should have the different parts 
desigcated by numbers or letters. The de- 
scription should explain the construction 
and operation of the device, referring to the 
various parts by the numbers or letters. The 
objects sought to be attained by the inven- 
tion should be stated. 

It is seldom practicable to make the prelim- 
inary examination or to prepare an applica- 

[2] 



tion for patent qq a mechanical device from 
a description alone, and drawings or a model 
should always be submitted. 

Upon receipt of the requsite information, 
I will make the preliminary examination in 
the Patent Office, and report the result, stat- 
ing the probabilities of securing the patent 
and its scope. If any patent is found which 
partly or wholly anticipates the invention, 
a copy will be sent to the client at the same 
time. Should it be found that the invention 
is unpatentable, the inventor is thus saved 
the cost of further proceedings. 

When the opinion as to patentability is 
rendered, the inventor will be informed as 
to the cost of obtaining a patent for the in- 
vention. 

The charge for this examination is $5.00 in 
advance, which is credited on attorney's fee, 
should the inventor proceed with the appli- 
cation. In other words, the preliminary 
examination costs nothing, provided the in- 
ventor applies for a patent through me. 

Co^t of a Taieni. 

While, until the invention is examined, it 
is difficult to state the exact cost, a patent 
upon a device of a simple nature may be ob- 
tained for $65.00. The fees are as follows : 

Government filing fee, $15.00. 

Drawings (per sheet), $5.00. 

Attorney's fee, $25.00. 

[3] 



Government final fee, due after patent is 
allowed, $20.00. 

These fees cover the entire cost of securing 
the patent, unless it is found during prosecu- 
tion that it is necessary to take an appeal, 
or the case becomes involved in an interfer- 
ence. However, appeals are seldom neces- 
sary, it usually being possible to obtain from 
the principal examiner in charge of a case 
all to which the inventor is entitled; and 
interferences are comparatively rare. 

The government fees are paid the Patent 
Office, the filing fee w^hen the case is filed, 
and the final fee after the application is al- 
lowed and before the issue of the patent. 

The number of sheets of drawings and the 
attorney's fee are dependent upon the char- 
acter and complexity of the device. For 
complicated inventions the attorney's fee 
and cost of drawings range higher ; or, where 
the invention is of such a character that prep- 
aration and prosecution will require very 
tedious work, the charges are made com- 
mensurate. 

However, as has been s rated before, I al- 
ways inform the inventor of the cost of 
obtaining a patent when report is made 
upon patentability. I make my charges as 
low as are consistent with expert and careful 
services. An application that is not properly 
prepared and prosecuted can only result in a 
worthless patent. 

[4] 



The government fees are the same, whether 
the invention is simple or complicated. 

^he Application, 

When the inventor decides to make appli- 
cation for a patent, after consideration of my 
report on patentability, he should remit to 
me, with his order to prepare the case, the 
government filing fee of $15.00 and §5.00 
for each sheet of drawings required. The 
drawings will be made and the application 
papers prepared and sent him for inspection 
and signature, to be returned with the bal- 
ance of attorney's fee. The case will be 
filed in the Patent Office immediately upon 
its return, and diligently prosecuted to issue. 

A complete application comprises the first 
fee of $15.00, a petition, specification with 
claims, and oath ; and drawings, model or 
Sj)ecimen when required. Almost all in- 
ventions are susceptive of clear illustration 
by drawings, and a model is very seldom 
required by the Patent Office. Specimens 
are sometimes called for in applications for 
patents on compositions of matter. 

The petition states the full name, resi- 
dence and post-office address of the peti- 
tioner, designates the title of the invention, 
and must be signed by the applicant. 

Tlie specification is a written description 
of the invention, and must conclude with 
specific and distinct claims of what the 
inventor regards as his invention. It 

[5] 



must be signed by the inventor or by 
his executor or administrator, and the signa- 
ture must be attested by two witnesses. 
Full names must be given, and all names, 
whether of applicants or witnesses, must be 
legibly written. 

The applicant must make oath that he be- 
lieves himself to be the original and first in- 
ventor or discoverer of that for which he 
solicits a patent. 

The drawings are intended to show the 
details of the invention, and they must be 
made according to certain strict rules of the 
Patent Office. 

•Vcopc of the ^ylpplication. 

Two or more independent inventions can- 
not be claimed in one application ; but where 
several distinct inventions are dependent 
upon each other and mutually contribute to 
produce a single result, they may be claimed 
in one application. 

Claims for a machine and its product must 
be presented in separate applications. 

Claims for a machine and the process in 
the performance of which the machine is 
used must be presented in separate appli- 
cations. 

Claims for a process and its product may 
be presented in the same application. 

[6] 



'Patentees. 

Joint inventors are entitled to a joint- 
patent ; neither of them alone can obtain a 
patent for an invention jointly invented by 
them. 

Independent inventors of distinct and in- 
dependent improvements in the same ma- 
chine cannot obtain a joint patent for their 
separate inventions. 

The fact that one person furnishes the 
capital and another makes the invention 
does not entitle them to make an application 
as joint inventors ; but, in such case, they 
may become joint patentees by making the 
proper assignment and recording it in the 
Patent Office. 

In case of death of the inventor, the ap- 
plication will be made by and the patent 
will issue to his executor or administrator. 
In case an inventor becomes insane, the ap- 
plication may be made by and the patent 
will issue to his legally appointed guardian, 
conservator, or representative. 

It is essential to a good patent that the speci- 
fication should clearly and completely 
explain the invention and its operation ; 
that the claims, upon which more than any- 
thing else the strength of the patent depends, 
should be carefully drawn ; that the dra wr- 
ings should be well executed and fully show 
the invention, and that expert and careful 

[7] 



attention should be given to prosecuting the 
case in the Patent Office. 

The specification and claims of a patent, 
particularly if the invention be at all compli- 
cated, constitute one of the most difficult 
legal instruments to draw with accuracy, 
and it is necessary to employ a skilled 
attorney to properly prepare and prosecute 
a patent case. 

In this connection, Rule 17 of the Patent 
Office says : ' * An applicant or the assignee of 
the entire interest (in an invention) may 
prosecute his own case, but he is advised, 
unless familiar with such matters, to employ 
a competent attorney, as the value of patents 
depends largely upon the skillful preparation 
of the specification and claims." 

Proceedings in the Patent Office are con- 
ducted in accordance with rules which are 
strictly adhered to, and those who are not 
conversant with the rules and practice of the 
office have great difficulty in prosecuting 
applications. 

Kjcammatton of Applications. 

Applications filed in the Patent Office are 
classified according to the various arts, and 
assigned to one of the examining divisions, 
where they are taken up for examination in 
the regular order of filing, those in the same 
class being examined and disposed of in the 
order in which the respective applications 
are filed. There are at present thirty-seven 

[8] 



examining divisions, each in charge of a 
principal examiner. 

Upon examination, an application is either 
allowed or objected to. If objection is made, 
it is the duty of the attorney to secure a fa- 
vorable reconsideration of the case or to 
amend the application to obviate objection 
and secure allowance of the patent. 

Most applications are objected to for one 
reason or another ; and it is here that care- 
ful prosecution on the part of the attorney 
is necessary, in order to secure for his client 
all to which he is entitled. 

It often happens that the divisions of the 
Patent Office are much behind in their work; 
and, for this reason, frequently an application 
is not reached for examination until some 
weeks after filing. Therefore, owing to the 
varying and uncertain conditions of the work 
in the Patent Office, it is impossible to state 
with certainty the time which will be re- 
quired to secure a patent. 

Issue of the T^aient, 

After allowance of an application, the 
patent issues subsequent to the payment of 
the final fee of $20.00. This fee is payable at 
any time within six months from date of 
allowance. 

An application which has become forfeited 
by reason of failure to pay the final fee within 
the required time may be renewed upon the 

[9] 



payment of a renewal fee of $15.00, after 
which the final fee is payable and the patent 
will issue. 

Appeals, 

It is often necessary in prosecuting an ap- 
plication to amend the case a number of 
times and present successive arguments why 
the patent should be granted. In most 
cases it is possible to secure the allowance of 
an application from the principal examiner 
having it in charge, but occasionally he per- 
sists in his objections. Then an appeal may 
be taken from this action. I always use 
every possible means, without sacrificing a 
client's interests, to secure allowance from 
the principal examiner, and thus avoid 
appeal and save to the client the additional 
costs. Fortunately, appeals are necessary in 
a comparatively few cases. 

When an applicant feels aggrieved because 
of any final action of a principal examiner 
which involves the merits of the case, he 
may appeal to the Board of Examiners-in- 
Chief, from that board to the Commissioner 
of Patents, and from him to the Court of 
Appeals of the District of Columbia. 

The government fee on taking an appeal 
to the Examiners-in-Chief is 110.00 ; to the 
Commissioner of Patents, |20.00 ; and to the 
Court of Appeals of the District of Columbia, 
$15.00. My charge for preparing and argu- 
ing an appeal is in accordance wdth the 

[10] 



character of the case and the services 
required. 

On certain interlocutory questions appeal 
may be made direct from a principal exam- 
iner to the Commissioner of Patents in 
person, without payment of a government 
fee. 

Interferences. 

When tv70 or more parties claim substan- 
tially the same patentable invention, an inter- 
ference proceeding is instituted in the Patent 
Office for the purpose of determining the 
question of priority of invention, and the pat- 
ent is granted to the person who proves to 
be the prior inventor. 

Although comparatively few cases become 
involved in interference proceedings, it is 
advisable for inventors to date, have wit- 
nessed, and preserve all drawings, models, 
and data which show or describe the inven- 
tion or any of its parts and the date of con- 
ception of the invention and the subsequent 
steps in its development, as such evidence is 
invaluable in interference controversies. In- 
ventions should be reduced to practice and 
applications for patents filed as soon as pos- 
sible, as an early filing date is of prime im- 
portance. 

A reissue patent is granted for the remainder 
of the term of the original patent to the orig- 

[II] 



inal patentee, his legal representatives, or 
the assignees of an entire interest, when the 
original patent is inoperative or invalid by 
reason of a defective or insufficient specifica- 
tion, or by reason of the patentee claiming 
as his invention or discovery more than he 
has a right to claim as new, provided the error 
has arisen through inadvertence, accident^ 
or mistake, and without any fraudulent or 
deceptive intention. 

MarKing Article4: '' Tatenied/^ 

Section 4900 of the Revised Statutes pro- 
vides that articles manufactured under a 
patent should have affixed the word 
'* patented ", together with the day and 
year the patent was granted ; or when, from 
the character of the article, this cannot be 
done, there should be affixed to it, or to the 
package wherein one or more of ihem is in- 
closed, a label containing the notice ; and in 
any suit for infringements, by the party fail- 
ing to so mark, no damages shall be recovered 
by the plaintiff, except on proof that the 
defendant was duly notified of the infring- 
ment, and continued after such notice, to 
make, use, or vend the article so patented. 

This statute can be complied with by 
marking the article or package thus : 
Patented, February 2, 1904. 

[12] 



U^e and 'PuhUciiy. 

Inventors often wish to be informed as to 
their rights and the advisability of manufac- 
turing and placing on the market their in- 
ventions before a patent is granted. 

Pending the consideration of an applica- 
tion for patent in the United States Patent 
Office, an invention may be manufactured 
and sold under the mark "Patent applied 
for." 

However, the publicity incident to such 
manufacture will subject the inventor to the 
danger of someone else surreptitiously claim- 
ing the invention as his own and applying 
for a patent thereon. Should this happen, 
the inventor will be put to the expense of 
interference proceedings in the Patent Office 
to establish his rights. 

Furthermore, premature manufacture and 
introduction might injuriously affect the va- 
lidity of patents which the inventor might 
wish to secure in foreign countries. 

For these reasons, it is safest not to give 
unnecessary publicity to your invention until 
after you have secured your patent pro- 
tection. 

*y*ale of 'Patents. 

I am engaged exclusively in the solicitation 
and litigation of patents, and the exacting 
duties connected with this practice leave me 
no time for selling patented inventions. The 
best person, in most instances, to sell a patent 

[13] 



IS the inventor himself; and I am always 
glad, when it is in my power, to gratuitously 
put an inventor in possession of such in- 
formation as will enable him to obtain the 
names and addresses of responsible persons 
who might purchase his invention. 

Inventors who haven't the funds for the 
purpose of securing patents upon their in- 
ventions frequently assign the entire or a 
part interest in them to others, in order that 
they may raise the necessary money from 
«uch sale for use in obtaining their patents. 
Yery often an inventor can interest someone 
in his invention and sell a part of it to him. 

Prospective purchasers of the whole or of 
;a part interest in an unpatented invention 
usually require some assurance that a patent 
€an probably be secured. A report from me 
as to probable patentability, such as is 
mentioned above under ** Preliminary Ex- 
amination," can readily be used to give this 
assurance. 

Assignment of "Patent. 

The property interest in a patent is trans- 
ferred by written assignment over the signa- 
ture of the assignor. The law provides that 
assignments may be made either of the 
whole or part interest in a patent, either be- 
fore or after the issue thereof. To be valid 
the assignment must be recorded in the 
Patent Office within three months from its 
date ; and it is essential that it be carefully 
prepared. 

[14] 



Carelessness in the preparation of, and 
failure to record, assignments have caused 
endless loss and litigation to purchasers of 
patents and patent rights. 

My charge for preparing an assignment of 
ordinary length is $5.00. The Patent Office 
charge for recording every assignment, agree- 
ment, power of attorney, or other paper, of 
300 words or under is $1.00 ; of over 300 
words and under 1000 words, $2.00 ; of over 
1000 words, $3.00. The expense of assign- 
ment is usually borne by the purchaser. 

Where an inventor, during the time he is 
perfecting his invention, ivishes to be ap- 
prised of the filing by others in the Patent 
Office of applications for patents on the same 
thing upon which he is w^orking, he may file a 
caveat in the Patent Office, stating the func- 
tions and the distinguishing characteristics 
of his invention. A caveat remains in force 
one year, and may be renewed for another 
year. Its only statutory function is to pre- 
vent the issue of a patent to another until 
after the caveator has notice of the interfer- 
ing application, and thus has opportunity to 
file an application and obtain judgment as 
to priority of invention through interference 
proceedings with his competitor. 

I seldom advise my clients to file caveats. 
Except in rare cases, they are of doubtful 
value. If an inventor has advanced his in- 

[15] 



vention to the stage where he has an opera- 
tive device, by far the best course is to file 
application for patent. Subsequent improve- 
ments can be claimed in subsequent applica- 
tions. 

The government fee for filing a caveat is 
$10.00; and the renewal fee is $10.00. My 
charge for preparing a caveat is usually 
about $20.00. 

A patent for a design may be obtained by 
any person who has invented any new, orig- 
inal, and ornamental design for an article of 
manufacture, not known or used by others 
before such invention, nor patented or de- 
scribed in any printed publication. 

Patents for designs are granted for the 
term of three and one-half years, or for seven 
years, or for fourteen years, as the applicant 
may in his application elect. The term for 
which a design patent is to run must be de- 
termined before the application is filed ^ as no 
change in such term can be made thereafter. 

The rules and practice followed in the 
solicitation of patents for designs are sub- 
stantially similar to those applicable to 
patents. 

Co^i of a 'Patent J^or a lye^ign. 

The government fee for a patent for a de- 
sign, payable when application is filed, is, 
for three and one-half years, $10.00; for seven 
years, $15.00 ; for fourteen years, $30.00. 
There is no final government fee. 
[i6] 



The attorney's fee in an ordinary case is 
$25.00. The charge for drawings is $5.00 per 
sheet, unless the design is unusually elab- 
orate. 

Trade-MarK.^. 

Trade-marks used in commerce with 
foreign nations or Indian tribes may be reg- 
istered in the Patent Office by their owners. 

The certificate of registration remains in 
force thirty years, and may be renewed 
under the same terms and for a like period 
at any time during the six months immedi- 
ately prior to the expiration of said term. 

The advantages of the registration of a 
trade-mark lie in the facts that registration 
serves to establish the date of adoption and 
an exact description of the trade-mark ; 
that registry is notice to the world, is prima 
facie evidence of ownership, and supplies 
the place of long use at common law ; and 
that registry gives the registrant certain 
rights in the United States courts which he 
would not otherwise possess. 

Co^t of a Trade-MarK,' 

The registration of a trade-mark costs 
$50.00— government fee $25.00, and attor- 
ney's fee $25.00. The government fee is 
payable when the application is filed. 
There is no final government fee. The 
attorney's fee includes the drawing of the 
trade-mark, unless it is very elaborate, and 

[17] 



preliminary examination to ascertain 
whether the trade-mark can probably be 
registered. 

Copyrights. 

Copyrights are granted for twenty-eight 
years. At any time during the six months 
immediately prior to their expiration they 
may be renewed for fourteen years 
longer. Title or description of the work 
must be recorded in the Library of Congress 
before publication. Upon publication, two 
copies of the work must be filed with the 
Librarian of Congress in order to perfect the 
copyright. 

No copyright can be protected against in- 
fringement unless notice of copyright is in- 
serted in every copy produced ; and, in 
case of a book, should be printed on the title 
page or upon the page immediately follow- 
ing. The preferable form of notice is 
as follows : Copyright (here insert year), by 
(here insert full name of claimant). The 
proper use of the notice is shown- by the 
notice of copyright of this booklet on the 
second cover page. 

My charge for securing copyright is $5.00. 
The government fee for recording title is 
fifty cents for production of a citizen of the 
United States, and $1.00 for production of a 
foreigner. The charge for a certified copy 
of record is fift^^ cents. 

[ i8 ] 



opinions on Infringements Validity 
and Title, 

Frequently persons wish to determine 
whether an article made or used by them in- 
fringes another's patent, or whether articles 
made or used by others infringe their pat- 
ents or those of others. The question also 
occasionally arises as to whether a patent in- 
fringes any other patent. 

The validity of patents is also often called 
into question. A thorough examination of 
the records of the Patent Office is necessary 
to determine validity. 

Searches of the assignment records of the 
Patent Office are made for prospective pur- 
chasers of patent rights to ascertain whether 
or not prospective assignors have clear titles. 
The same precautions should be taken in this 
regard in buying patent rights as are taken in 
examining the records of deeds in buying 
real estate. The validity of a patent should 
also be looked into before purchasing any in- 
terest therein. 

I am prepared to make comprehensive 
searches and to render opinions as to in- 
fringement, validity and title of patents ; 
and also as to trade-marks. 

Litigation. 

Suits before the courts involving patents, 
trade- marks, or copyrights are carefully de- 
fended or prosecuted by me, and my expe- 

[19] 



rience in this branch of law renders me 
capable of conducting such suits with 
facility. 

Copies of Tatents. 

A number of copies of each patent issued 
is printed by the Patent Office, and I can 
furnish such copies at the rate of ten cents 
apiece when the number of the patent is 
given. When ordering copies it is also well 
to give the title of the invention and the 
date of the patent. Where the number of 
the patent, or the title and date, cannot be 
given, a search is necessary to identify from 
among the great number of patents the one 
desired. A charge is made for this search in 
accordance with the time required. Over 
790,000 patents have been issued. 

Foreign 'Paienis. 

Almost all foreign countries grant patents, 
and in the more important ones they are of 
great value. I am prepared to secure foreign 
patents with the least delay, and can quote 
very low rates for this service. Special rates 
can be given when patents are soli^ited in 
several countries simultaneously. The mat- 
ter of foreign patents should be attended to 
before the issue of the United States patent. 

Value o_f Iri'Ve fit ions. 

Much money has been made on simple 
inventions of seeming insignificance. Be- 
cause an invention makes but a slight change 
[20] 



in an existing device is no indication that 
the change is of no value. 

In these days, when everything in manu- 
facturing establishments is highly systema- 
tized and much thought is given to economy 
of production, a change which may mean a 
decrease of only a fraction of a cent in the 
cost of one article may mean the saving of 
thousands of dollars in a day's output. 

There is a great demand for just these 
small improvements which tend to decrease 
the cost of existing devices or processes, and 
those which serve to produce better articles 
of manufacture. 

If you have made a change in a machine, 
and that change simplifies the machine or 
causes it to produce a better or increased 
output, or if you have made an improvement 
in an article of manufacture, secure a patent 
and receive some reward for the time you 
have spent in developing the invention. 

Delays are dangerous in patent matters. 
Do not delay filing application for patent 
after the invention is completed, because 
someone else might apply for patent on the 
same thing you have invented while you are 
thinking about it. 

If you have invented or discovered any 
new and useful art, machine, manufacture or 
composition of matter, or any new and use- 
ful improvement in them, or any new, origi- 

[21] 



nal and ornamental design for an article of 
manufacture, your rights should be protected 
by a patent. If you are the manufacturer or 
dealer in any particular make or brand of an 
article of commerce, your goods should be 
distinguished by a registered trade-mark. If 
you are the author, designer or proprietor of 
any book, map, chart, dramatic or musical 
composition, or work of art, your title to it 
should be reserved by copyright. 

As has been stated before, it is necessary 
to have first-class legal assistance in all mat- 
ters relating to patents. I have had long 
experience in the transaction of patent busi- 
ness, and am familiar with all branches of 
the profession. I offer expert and faithful 
service in the preparation and prosecution 
of patent cases of every nature. I am a 
member of the bar of the Court of Appeals 
of the District of Columbia, to which appeals 
lie from the Commissioner of Patents, of the 
Supreme Court of the District of Columbia, 
and of the Supreme Court of the United 
States ; and practice in all of these courts 
and other courts of the United States, as well 
as before the Patent Office. 

The advantages of an attorney located at 
Washington over those located elsewhere 
are many. The Washington attorney has 
ready access to the Patent Office and its 
archives. He transacts his business directly 

[22] 



with the Patent Office, and not through an 
associate at Washington, as do other attor- 
neys, thus avoiding the delays and unsatis- 
factory service incident to frequent corre- 
spondence between the attorneys. When 
personal interviews with the Patent Office 
examiners are advisable, the Washington 
attorney can easily and expeditiously con- 
duct them. The attorney located away from 
Washington has to either employ his associ- 
ate at Washington to conduct the interviews 
or come to Washington himself at the ex- 
pense of his clients. 

T^reser-Oaiion of Secrecy. 

All correspondence, data, drawings, mod- 
els, and other information of whatever char- 
acter, pertaining to my cases, are held in the 
strictest confidence, and the files of my office 
are accessible only to those connected there- 
with. 

All business being conducted in a confi- 
dential manner, no information can be given 
cencerning a case to anyone other than the 
client without properly verified authority 
from him. 



The object of this booklet is to get in 
touch with you, and to place before you in a 
brief and concise manner such information 
as will enable you to intelligently proceed to 
secure patent protection for an invention.

Many questions arise with respect to indi- 
vidual cases which cannot be anticipated in 
a booklet of general application, and I will 
be glad to have you correspond with me 
concerning your case, whether it may lead 
to business or not. 

I w^ill be glad at any time to answer any 
questions which may occur to you in connec- 
tion with patents, trade-marks, or copyrights. 

A few letters from clients, selected from 
the great number of this character which I 
am constantly receiving, are published in 
the latter part of this booklet. It shall be 
my pleasure to render the same satisfactory 
service to you that I have previously ren- 
dered to clients. Any of them will be glad 
to say to you by letter what they have said 
to me about my services. I would suggest 
that in writing to them you enclose stamp 
for reply.

Bond Building, 
Washington, D. C. 

Dear Sir : I am pleased to inform you that 
patent papers, No. 724,008, for hydro-carbon 
burner, arrived on the 3d inst., just four days 
from the time they were issued. I am very 
highly pleased with the way you do business, 
and assure you that all my futuie business in 
Washington of any legal nature will be placed 
in your hands. I will always recommend 
you to any one needing service in your line 
at Washington. When I first employed you, 
I had written to another attorney, at the same 
time I wrote you. You had my application 
for patent No. 705,530 filed in the Patent 
Office before I received reply from the other 
attorney. Promptness in business matters is 
what counts, especially in patents. You were 
just as prompt in the second patent you ob- 
tained for me as you were in obtaining the 
first. The writer was absent from the city, 
hence the delay in acknowledging receipt of 
your favor of the 1st inst. I am very busy at 
present, but hope to take up the matter re- 
garding other patents soon. 

Thanking you for past favors, I remain. 
Yours very truly, 

J. F. HIGGINS.

My Dear Sir : Your favor of the 8th, 
enclosing my patent No. 733,140 for corn-

fully appreciate the neatness of the draw- 
ings, the comprehensive style of the specifi- 
cation, and the solid wording of the claims, 
is only half of it. I find that 1 never fully 
know your best efforts until I receive my 
patents.
